What is the lateral surface area of a cone that had a diameter of 7 inches and a slant height of 10 inches? 12.25 pi in.^2 17.5 pi in.^2 35 pi in.^2 70 pi in.^2

Answer :

Answer:

the lateral surface area of a cone is 35π inches^2

Step-by-step explanation:

Given that

The diameter is 7 inches

And, the slant height is 10 inches

We need to find out the lateral surface area of the cone

We know that

The Lateral surface area of the cone is

= πrl

= π × 7.5 ÷ 2 × 10

= 35π inches^2

Hence, the lateral surface area of a cone is 35π inches^2
